Klondex Comments on Report

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Sep 10, 2014) - Klondex Mines Ltd. (TSX:KDX)(OTCQX:KLNDF) ("Klondex" or the "Company") provides comments on Mine Safety and Health Administration's ("MSHA") final report of the accident at the Midas mine.

Brent Kristof, Klondex Mines Chief Operating Officer commented, "Klondex recently received MSHA's report on the tragic accident resulting in the death of Rich Otto at our Midas Mine. The tragic loss of our co-worker, friend, and employee affected us very deeply. Rich Otto was an experienced miner with over 32 years in mining. He was organized, safety conscious and was often used to train other employees. He would never have allowed himself to work in the conditions alleged by MSHA. Safety is and has always been our first priority at Klondex. Our Fire Creek Project was recently recognized for its outstanding safety performance by the Nevada Mining Association in the small underground mine category. We applied this same level of safety to our Midas Mine upon its acquisition in 2014."

Mr. Kristof continued, "Despite our complete cooperation with MSHA during the investigation, we believe that MSHA failed to consider critical information and reached conclusions which don't appear to be supported by the evidence in the report. The report fails to analyze root causes of the accident or explain how the physical evidence and facts support its conclusions. We have contested the enforcement actions taken by MSHA and are continuing to challenge the unsupported allegations in the report."

Cautionary Note Regarding Technical Information and Forward-looking Information

A production decision at the Fire Creek Project has not been made by Klondex, as it is still in the bulk sampling phase. Although a production decision at the Fire Creek Project has not been made, the mineralized material extracted from the Fire Creek Project under the bulk sample permit is processed through the Midas mill.

A production decision at the Midas Mine was made by previous operators of the mine, prior to the completion of the acquisition of the Midas mine by Klondex and Klondex made a decision to continue production subsequent to the acquisition. This decision by Klondex to continue production and, to the knowledge of Klondex, the prior production decision were not based on a feasibility study of mineral reserves demonstrating economic and technical viability prepared in accordance with NI 43-101. Readers are cautioned that there is increased uncertainty and higher risk of economic and technical failure associated with such production decisions.
